METAL WEATHER-STRIPPING.

Specification of Letters Patent.

Patented July 3, ildil'ti.

Application filed June 8, 1916. Serial No. 102,398.

To all whom it may concern Be it known that I, ALFRED LANE, a

itizen of the United States, and aiesident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Metal WVeather-Stripping, of which the following is a specification.

This invention relates to metal weather stripping particularly adapted for swinging doors and casement windows.

The object of the invention is to weather strip a door or swinging window so as to keep out the weather, and to prevent dripping from the bottom of the swinging door or window when opened on to the floor.

A further object is to make it easy to in ,stalland repair the weather stripping, and

to prevent it from damaging the woodwork of the door or window.

The invention consists in the shape and arrangement of the flexible strips and the sill strip shown in the accompanying drawing, and claimed in the appended claims.

The drawing shows a cross-section through the top of the frame and the sill of a door or casement window, the free edge of the door being shown in elevation. The middleof the door is broken away to disclose one-side of the door frame, and weather-stripping therefor.

The top and sides of the door frame 10 are provided with spring bronze weather strips 11, which are slightly narrower than the thickness of the door 12 and are arranged in the space between the edges of the door and the frame. The edges of the strips 11 toward the inside of the door are nailed to the door frame, their free edges extending toward the angles of the door frame and bearing against the edges of the door near its outer side. The free edges of the strip 11 are rolled back on the side toward the door frame to form beads 13 which stiffen the strips and prevent them from vibrating when the wind blows.

The bottom of the door has a spring bronze strip 14 nailed along its inner edge, the outer edge of the strip being turned up outside of the lower outside edge of the door and having a bead 15 at its extremity. rigid brass Z-shaped coverstrip 16 1s screwed along the lower edge of the outside of the door, the lower flange of the cover strip being spaced away from the door to house the beaded edge 15 of the spring brass bottom strip 14. The lower edge of the cover strip 16 has an inturned flange 17 which lies below the head 15 and keeps it 111 place under the cover strip. The spring of the metal of the bottom strip 14 tends to keep it away from the bottom of the door as far as the cover strip will permit it to go.

The door sill 18 has a metal sill strip 19* secured along its top and extending across the door opening from side to side. The sill strip has an upwardly projecting corrugation 20 along it near its outer edge, and the ends of the corrugation terminate at the lower ends of the free edges of the strips 11 where they bear against the door. The bottom strip 14- on the door has a mating depression 21 in it which fits over the corrugation 20 when the door is closed. The outer edge of the bottom strip contacts with the outer edge of the sill strip in closed position of the door.

The door swings inwardly, and there is sufficient play between the bottom strip 14: and the bottom of the door to permit the outer edge of the bottom strip to ride over the corrugation 20 in the sill strip without binding. The corrugation 20, brushing under the outer edge of the bottom strip, scrapes ofl' any water which may have driven under the outer edge of the door and pre vents it from being carried over the floor by the door when it is opened. The outer edge of the bottom strip is rounded up and the corrugation 520 is rounded enough to permit the edge of the bottom strip to ride over the corrugation easily when the door is closed.

It is evident that the invention may be applied to the meeting edges of double windows, folding doors and windows, and the like, and it is not restricted to the precise shape and arrangement of the parts shown in the drawings.

I claim the following as my invention:

1. Weather stripping for an inwardly swinging door of the character described, comprising. flexible metal side strips secured to the framealong their inner edges with their free edges spaced from the angles of the frame and contacting with the edges of the door near its outer face, a fixed sill strip secured to the door sill and provided with an upwardly projecting rib positioned beneath the door near its outer face, the ends of said rib being disposed in alinement with said contacting portions of said flexible side strips, and a flexible sill strip arranged beneath the bottom of the door and having a groove in it to receive said rib, said flexible sill strip making contact with said fixed sill strip outside of and over said rib, the inner edge of said flexible sill strip being secured to said door and the outer edge being turned up and fitting loosely in a downwardly opening recess along the outer edge of said door.

2. Weather stripping for an inwardly swinging door of the character described, comprising flexible metal side strips secured to the frame along their inner edges with their free edges spaced from the angles of the frame and contaiiting with the edges of the door near its outer face, a fixed sill strip secured to the door sill and provided with an upwardly projecting rib positioned beneath the door near its outer face in the plane of the lines of contact between the edges of the door and said contacting portions of said flexible side strips, and a flexible sill strip arranged beneath the bottom of the door and having. a groove in it to receive said rib, the inner edge of said flexible sill strip being secured to said door and the outer edge being turned up and fit- ALFRED M. LANE.
